Kev piav qhia
EDFA, uas sawv cev rau erbium-doped fiber ntau amplifier, yog ib qho amplifier siv dav hauv kev sib txuas lus fiber ntau. EDFA muaj ntau yam zoo hauv kev sib txuas lus kho qhov muag, raws li tau tham hauv qab no.
Ua ntej, EDFA muaj qhov nce bandwidth loj dua. Nyob rau hauv lub wavelength ntau ntawm 1550 nanometers, qhov nce bandwidth ntawm EDFA tuaj yeem mus txog qib kaum ntawm nanometers, uas ua rau EDFA los txhim kho cov teeb liab multiplexed kom lawv tsis poob thaum sib kis.
Qhov thib ob, EDFA tau nce siab. Txij li thaum EDFA siv erbium-doped optical fiber, erbium ions yuav raug hloov hluav taws xob thaum zoo siab los ntawm laser wavelength, ua rau muaj hluav taws xob tawg thiab tso tawm photons tib lub sijhawm. Cov photons tuaj yeem ua rau kev hloov hluav taws xob hauv lwm cov erbium ions, yog li ua kom qhov nce ntawm lub amplifier. Yog li ntawd, qhov nce ntawm EDFA tuaj yeem siab heev, feem ntau ncav cuag ntau dua 30 dB.
Thib peb, EDFA muaj lub sijhawm teb ceev ceev. Piv nrog rau semiconductor amplifiers thiab Raman amplifiers, EDFA muaj lub sij hawm teb luv dua, feem ntau ntawm qib microsecond. Qhov no ua rau EDFA kom teb tau zoo dua rau cov kev hloov pauv sai sai hauv cov cim thiab txhim kho kev ua haujlwm yooj yim thiab cov lus teb ceev.
Thaum kawg, EDFA muaj kev ruaj ntseg. Txij li thaum EDFA siv erbium-doped fiber ntau, kev faib tawm ntawm erbium ions yog qhov ruaj khov, yog li EDFA muaj kev ruaj ntseg zoo thiab kev ntseeg siab. Nyob rau tib lub sijhawm, qhov ntsuas kub qis dua siv los ntawm EDFA kuj tseem muaj txiaj ntsig zoo rau kev txhim kho kev ruaj ntseg ntawm lub tshuab hluav taws xob.
EDFA feem ntau yog siv nyob rau hauv kev sib txuas lus kho qhov muag mus ntev thiab kho qhov muag amplifier systems. Hauv kev sib txuas lus kho qhov muag, EDFA tuaj yeem siv los txhim kho cov teeb liab lub zog thiab kev ncua deb kom ua tiav kev sib kis mus ntev; nyob rau hauv optical amplifier systems, EDFA yuav siv tau los amplify cov zis ntawm lasers thiab ua kom lub zog kho qhov muag.
Nyob rau hauv luv luv, EDFA yog ib qho amplifier nrog kev ua tau zoo heev thiab muaj cov ntawv thov dav dav hauv kev sib txuas lus kho qhov muag. Los ntawm muab kev ua si tag nrho rau nws qhov zoo, peb tuaj yeem txhim kho qhov nrawm, kev ncua deb thiab kev ntseeg siab ntawm kev sib txuas lus kho qhov muag thiab ua tiav kev sib txuas lus kho qhov muag kom nrawm dua thiab ruaj khov.
